[boost] Posix Timers (date_time versus timer)

Does anyone have any idea about how the methods for computing time compare 
on a unix/linux system? Specifically I am interested in resolution and 
reliability.

using namespace boost;
using namespace date_time;

{
  timer t;
  // code ...
  double sec = t.elapsed();
}

{
  ptime start = microsec_clock::local_time();
  // code ...
  time_duration total = microsec_clock::local_time() - start;
  double sec = total.seconds() + (1000000000 / total.fractional_seconds());
}

Thanks
